The area of no danger, light danger, medium danger, severe danger and extreme severe danger regions respectively are 278 000, 288 000, 217 000, 127 000, 15 000 km^2. Furthermore, the counties in the UYRW are classified into four classes based on the hazards degrees in each county. The number of severe danger, medium danger, light danger and no danger counties respectively are 49, 82, 77 and 105. The assessment results will be provided for the hazards forecasting and mitigation in the UYRW and ongoing regionalization of Main Function Regions in China as data and technique framework.展开更多

According to these comments, UCP valued technologies and tools exces- sively （＂task＂）, and did not pay much attention to methodology （＂discipline＂）. Actually, both ＂task＂ and ＂discipline＂ are geographical wings, especially in the time of ＂big science＂. Enlightenment from UCP and its comments is the strategic direction that should be balanced between ＂task＂ and ＂discipline＂, GS should be a three-dimensional construct of a disciplinary system, methodology, and technologies and tools, and this system should be scientific hu- manism based on scientific spirit and directed by humanism. During the last 60 years, Chi- nese geographers devoted themselves to GS, including practice and theory. Obviously pro- gress and outlook are proposed as interdisciplinary GS, Earth Surface Sciences （ESS） and Geographical Construction （GC）. The disciplinary system of GS is very complex, and is composed of such human knowledge domains as sciences, technologies, engineering, and philosophy. The main mission is to research the open, complex, and macro earth system （not only scientifically, but also humanistically）, and one significant methodology is ＂comprehen- sive integration of qualitative and quantitative means＂ （CIQQM）. At the same time, another changing direction in Chinese geography is Human-Economic Geography （HEG）.展开更多

However,the region faces a problem of paucity of data on treeline characteristics at the regional and landscape scales. Therefore,we used Remote Sensing(RS),and Geographic Information Science(GIS) approaches to investigate cross-scale interactions in the treeline ecotone. Additionally,European Space Agency land cover map,International Center for Integrated Mountain Development(ICIMOD) land cover map,ecological map of Nepal,and United States Geological Survey Shuttle Radar Topography Mission-Digital Elevation Model were used to analyze treeline pattern at the regional scale. Digital Globe high-resolution satellite imagery of Barun(eastern Nepal) and Manang(central Nepal) were used to study treeline patterns at the landscape scale. Treeline elevation ranges from 3300-4300 m above sea level. Abies spectabilis,Betula utilis,and Pinus wallichiana are the main treeline-forming species in the Nepal Himalaya. There is an east to west treeline elevationgradient at the regional scale. No slope exposure is observed at the regional scale; however,at the landscape scale,slope exposure is present only in a disturbed area(Manang). Topography and human disturbance are the main treeline controlling factor in Barun and Manang respectively.展开更多

The main indices include the number and proportion of international manuscripts, published articles, downloads, impact factors, total cites, cited journals, citing journals, and highly cited papers. Up to 2015, the JGS had received manuscripts from authors in 80 countries and published papers from authors in 32 countries. The citation indices of JGS show increasing trends in the last seven years. The impact factor of the JGS increased from 0.518 in 2009 to 1.923 in 2015. Total cites increased from 157 in 2009 to 1276 in 2015. The international full-text downloads of the JGS increased year by year, and the number of downloads in 2015 was about three times that of 2009. The published papers were considered to be influential. The results of this study provide scientific guidance for the development of the Journal of Geographical Sciences and can be used to improve the quality of other Chinese geographical journals.展开更多

Together with other branches of information geography, it seeks the balance between universality and particularity of geographical laws by combining methods from neighboring disciplines(such as big data and artificial intelligence) with the special nature of geographical spaces. Meanwhile, at the core position of the geography discipline, GIScience makes geography stronger from two directions: "strengthening the theoretical foundation" and "improving technology and promoting the practical applications".展开更多
